What is blacklisted ip?

Answer 1

A blacklisted IP is an internet Protocol address that has been identified as a source of malicious activity, such as spamming or hacking, and is thus included on a list that restricts its access to certain networks or services. This can occur due to various reasons, including the sending of unsolicited emails or being part of a botnet. Being blacklisted can significantly impact a user's ability to send emails or connect to specific websites, as many organizations use these lists to filter out potentially harmful traffic. To resolve this, the owner of the blacklisted IP typically needs to address the issues leading to the ban and request removal from the blacklist.
